Addition of MEMORY_TABLE use in write to Db2

[dzilio]

Description

Fixes # (issue)

This will allow the sink operator when used with Db2 to be able to use the MEMORY_TABLE function to batch rows in a blob and use that function in a subselect to pass the BLOB to an INSET in JDBC to Db2 LUW for v11.5.9 or higher releases.

The config/jdbc-sink.properties needs to have: insert.function.value=memory_table added to activate using the function for inserts. If not used the Db2 inserts will revert to a simple JDBC insert statement as was in the original sink code.
